Spin-split superconductivity in triple-hybrid materials

ORAL  · Invited

Abstract

Recently developed semiconducting InAs nanowires with epitaxial superconducting Al and ferromagnetic insulator EuS shells display induced superconductivity with a sizable Zeeman-like splitting at zero external magnetic field. The intricate interplay between spin-orbit coupling, magnetic domains, and superconducting phase coherence gives rise to unique ground states and corresponding electrical properties. In this talk, I will present some of the rich phenomenology emerging in these materials.
